Patent DE-2652598-A1 (DE)
Title: Electrolytic waste sludge detoxification - by automatic metering of chemical additive between supply and machine
Inventor: GOSGER PETER
IPC: C25F7/02
Filed: 1976-11-19
Abstract: A detoxification process for the waste sludge of electrolytical metal working factories uses a chemical additive to keep the poisons discharged from the electrolyte purification below a predetermined limit. The additive is introduced into the electrolyte in the supply circuit between the storage tank and the electrolytical processing machine. The electrolyte is passed into the purification device with a reduced content of toxic matter. This is a simpler process than the known detoxification methods of waste sludge. The manual treatment which is a health risk is eliminated and the disposal has been facilitated.

Title: Hand drill screwdriver attachment - has coupling members rotating in housing and spring loaded apart when unloaded
Inventor: STILTZ ERWIN DIPL ING
IPC: B25F3/00
Filed: 1976-11-27
Abstract: The screwdriver attachment is for fitting to a power-operated hand drill, having a housing (4) clamped to the neck of the drill. A coupling member (5) rotates in the housing, having mating faces bearing against the spanner flats on the drill spindle (11), and is coaxial to a screwed spindle forming the other coupling member (6), which also accommodates the tool and rotates and slides in the housing. When not on load, the two members are held out of engagement by an elastic component (14, 15). This component can be a spring-loaded ball, both spring and ball being accommodated in a bore (13) in the second member (6). The ball acts against the first member (5), and the spring against a stop (17) on the second one.

Title: Pulse delay circuit giving independently variable pulse edges - has output of first monostable multivibrator connected to two parallel monostables and separate potentiometer for each monostable
Inventor: WAGNER HORST
IPC: H03K5/13
Filed: 1977-06-01
